Bourbon Pricing Tiers

A little background: I've always been a whiskey drinker, but I've really started to get in to it the past year or so. The more I pay attention to what's on the shelf instead of just grabbing the same old thing, I'm starting to notice what you can get for certain prices.

I'm a "value" guy. I try to get the absolute most for my money. I don't buy the most expensive stuff, instead, I usually find something in the middle of the road price wise that is almost as good as the premium items.

So, lets relate this to bourbon, shall we?

What does everyone find to be the best bourbon value in the following price ranges? (for a 750mL)

under $10

$10 - $15

$15 - $20

$20 - $30

$30 - $50

over $50

Seems to me there are a few peers a each price point, and each jump up in price also represents a similar jump in quality.
Let me throw out some names to start the discussion:

Re: Bourbon Pricing Tiers

There are some older threads along this line, but they were before I became a member so I haven't played yet. Given my experiences and Atlanta area prices, focusing on value . . .

under $10
The easy one here is VOB 90. To an extent, all bourbon is a good value and that can be seen here; EW, AA, etc., are in here, and drinkable for under a ten-dollar bill is a great thing (I even know a lady who loves Old Crow), but the VOB 90 would be a good value even a tier or two up.

$10 - $15
Actually harder. A lot of the "base bourbons" are priced here for me (JB white, OF 86, etc.), so see above. Prefer VOB 90 to anything here.

$20 - $30
Here the tier seems too wide. I see a real difference in the low $20's and the high $20's. A perfect example is that WT 101 is $21 and Russell Reserve is $29. Both good values, but it feels funny to list them as "equals." Also
OGD 114
ORVW 10 107
Knob Creek

over $50
Haven't felt the need to go over $50 yet. But here I'll mention Sazerac rye that I got in the high $40's. It could get priced pretty far into this tier before I would start questioning whether it was a good value.
